Description
TECHNICAL FIELD
[0001] The present invention relates to a car, and particularly, to
a separated anti-collision car.
BACKGROUND
[0002] With the rapid development of global economic technology,
the popularizing rate of cars is greatly increased. However, the
traffic casualty accidents caused correspondingly are also greatly
increased. The safety of the car has been a main index to measure
the value of the car. Specially, the anti-collision performance
(frontal collision) is even the important guarantee of the safety
of the car. At present, the collision safety system of the car with
mature configuration is mainly composed of a safety belt and a
supplementary restraint system, which increases the protection
ability to the driver and passenger to a certain extent. However,
the current car collision standard is basically measured according
to a condition of about 80 km/h speed per hour, but the speed per
hour of most injury accidents caused by collision is actually more
than 80 km/h. Therefore, the practicability of the anti-collision
index is very limited. Consequently, a challenge on the safety of
the collision at the speed per hour of more than 80 km/h is
presented.
[0003] Data shows that, collision injury of the car mainly has two
types: one is the injury caused by severe transformation of the car
body under the impact of an external force, which hits against and
squeezes the bodies of the driver and passenger; and the other is
that the speed of the car in a high-velocity motion is reduced to
zero in a relatively short period and in a condition of rest after
collision, so as to generate a huge accelerated speed, which leads
to viscera damage of the human body to cause the death.
SUMMARY
[0004] In order to overcome the problem of the prior art, an object
of the present invention is to provide a split anti-collision,
which can be adopted to greatly increase the anti-collision safety
of the car and protect the human body from being injured.
[0005] The object of the present invention is achieved through the
following technical solutions.
[0006] A separated anti-collision car comprises a frame and an
independent passenger cabin, wherein the independent passenger
cabin is arranged on the frame separately, a connected part between
a front part of the independent passenger cabin and the frame is
provided with a wedge-shaped slope mutually matched with the two,
the slope is provided with a damping supporting rod separating the
independent passenger cabin from the frame during collision, one
end of the damping supporting rod is fixed on the frame, and the
other end is connected to the independent passenger cabin; and a
back part of the independent passenger cabin is hinged with the
frame through an elastic expansion rod.
[0007] In the present invention, an end of the damping supporting
rod is fixed on the frame and is located on an upper end of the
wedge-shaped slope; and the other end of the damping supporting rod
is connected to a bottom end of the wedge-shaped slope at the front
part of the independent passenger cabin. A locking device is
arranged between the frame and the independent passenger cabin and
mutually matched with the two.
[0008] The present invention is considered as two parts while
designing the car body, i.e., the car is divided into two
independent parts comprising the passenger cabin and the frame. The
passenger cabin and the frame are closely connected into a whole
through a locking system under a normal condition, so as to
guarantee that no vibration and noise are caused during driving.
Once collision occurs, the locking system is opened automatically,
so that the passenger cabin and the frame are converted into a
separable state. The passenger cabin firstly generates an upward
thrust under the extrusion of the wedge-shaped connected part of a
front engine part, and then the passenger cabin rotates in a
longitudinal plane with an elastic connected point between the
passenger cabin and the rear frame as an axis under the effect of
initial kinetic energy. In order to prevent the front part of the
passenger cabin from going up too quickly, a follow-up damping
supporting rod is arranged between the lower side of the front end
of the passenger cabin and the frame for buffering the rising
velocity of the front end, which may fall back slowly after the
front end of the passenger cabin rises to a limit height. Through
the system above, when the car is collided, there is still much
time to gradually decrease the speed of the passenger cabin, so as
to greatly reduce the huge accelerated speed suffered by the driver
and the passenger. Meanwhile, since the passenger cabin gets out of
a squeezed state on a horizontal direction early, the person in the
cabin is avoided from mechanical injury, and the combined action of
the original air sacs and safety belt can basically ensure that the
driver and the passenger can be prevented from injury. Moreover,
since the passenger cabin is basically kept in good condition, the
person in the cabin may leave quickly after collision to avoid
injury of secondary disaster (such as fire and explosion).
[0009] The present invention aims at two types of injuries caused
by car collision. Firstly, a wedge-shaped connecting design between
the engine part and the passenger cabin firstly guarantees that the
transformation of a car head may generates an upward thrust to push
the passenger cabin to upward side instead of delivering to the
passenger cabin during collision to lead to the transformation of
the passenger cabin. Secondly, since the absorbed energy and
transformation of the car head are very limited during collision,
and the period is very short, even if the mechanical injury is
avoided, the huge accelerated speed may also lead to injury.
Therefore, the present invention fully uses the limited space above
the engine of the car head to extend the deceleration time of the
passenger cabin to the utmost extent, and convert the accelerated
speed on the horizontal direction directly suffered by the person
in the cabin into centripetal acceleration on the vertical
direction, so that the accelerated speed suffered by the human body
is greatly reduced, which may be known from a theoretical formula
of accelerated speed. For an object in a high-velocity motion, the
acceleration magnitude will be greatly reduced the time is
increased by 0.5 Se in the process of deceleration to a static
state. However, the accelerated speed which can be borne by the
human body shall be no more than 10 g. Thus it can be seen that, if
the decelerated time reaches to 1 S, the accelerated speed borne by
the human body is 3.4 g, which can be borne by the human body
safely, and then it is safe.
[0010] The present invention has the advantages and technical
features as follows.
[0011] 1. The present invention is designed based on the original
car structure and safety system, which does not change the
structure and the appearance of the car, and only separates the
passenger cabin and a chassis at a combined part between the
passenger cabin and the engine. Therefore, the technology is
simple, and the increased cost is limited.
[0012] 2. The passenger cabin is processed as an independent
entirety. The passenger cabin may be squeezed upwardly under the
wedge-shaped effect at the connected part between the passenger
cabin and the engine during collision instead of leading to
deformation of the passenger cabin, so as to prevent the person
from suffering mechanical injury caused by the deformation of the
passenger cabin during collision. Meanwhile, since the passenger
cabin may not be deformed, which guarantees that the person can
leave the passenger cabin in case of danger, so as to avoid
suffering secondary disaster (fire hazard, explosion and collision
of other cars) caused by collision.
[0013] 3. Both the back side and the front side of the passenger
cabin are provided with elastic damping rods and other devices to
guarantee the separation of the passenger cabin and the uniformity
and stability while falling back, so as to guarantee the safety of
person to the utmost extent.
[0014] 4. None transmission oil-ways and mechanical drive parts of
the passenger cabin, the chassis and the engine are in a whole.
Safe separation processing for emergency may be conducted on the
connected part between the passenger cabin and the engine and the
chassis, so as to avoid the obstruction during the separation
process of the passenger cabin, and the leakage after separation,
so as to guarantee the safety.

independent passenger cabin 2, wherein the independent passenger
cabin are arranged on the frame separately, a connected part
between a front part of the independent passenger cabin and the
frame are provided with a wedge-shaped slope mutually matched with
the two, the slope is provided with a damping supporting rod 3
separating the independent passenger cabin from the frame during
collision, one end of the damping supporting rod is fixed on the
frame, and the other end is connected to the independent passenger
cabin; and a back part of the independent passenger cabin is hinged
with the frame through an elastic expansion rod 4. One end of the
damping supporting rod is fixed on the frame and is located on an
upper end of the wedge-shaped slope; and the other end of the
damping supporting rod is connected to a bottom end of the
wedge-shaped slope at the front part of the independent passenger
cabin. A locking device is arranged between the frame and the
independent passenger cabin and mutually matched with the two. The
elastic expansion rod may be a spring.
[0018] The passenger cabin and the frame are closely communicated
into a whole through a locking system under normal condition, so as
to guarantee that no vibration and noise are caused during driving.
The locking system may be an openable multi-point clenching system.
Once collision occurs, the locking system is opened automatically,
so that the passenger cabin is separated from the frame. The
passenger cabin firstly generates an upward thrust under the
extrusion of the wedge-shaped connected part of a front engine
part, and then the passenger cabin rotates in a longitudinal plane
with an elastic connected point between the passenger cabin and the
rear frame as an axis under the effect of initial kinetic energy.
In order to prevent the front part of the passenger cabin from
going up too quickly, a follow-up damping supporting rod is
arranged between the lower side of the front end of the passenger
cabin and the frame for buffering the rising velocity of the front
end, which may fall back slowly after the front end of the
passenger cabin rises to a limit height. Through the system above,
when the car is collided, there is still much time to gradually
decrease the speed of the passenger cabin, so as to greatly reduce
the huge accelerated speed suffered by the driver and the
passenger. Meanwhile, since the passenger cabin gets out of a
squeezed state on a horizontal direction early, the person in the
cabin is avoided from mechanical injury, and the combined action of
the original air sacs and safety belt can basically ensure that the
driver and the passenger can be prevented from injury. Moreover,
since the passenger cabin is basically kept in good condition, the
person in the cabin may leave quickly after collision to avoid
injury of secondary disaster (such as fire and explosion).
